7. “I know” – Star Wars: The Empire Strikes Back (1980)

When Princess Leia confesses her love to Han Solo, the original script had Han responding with "I love you too." Harrison Ford knew that Solo's character would not be that sentimental so he changed it to the now iconic line "I know." This line captured Solo's roguish charm and became one of the memorable moments for fans.
